What is Qbrexza?
Qbrexza is a prescription medication used to treat axillary hyperhidrosis, which is excessive underarm sweating [1]. It is available as a topical solution applied using a cloth wipe [1]. The active ingredient in Qbrexza is glycopyrronium tosylate [1].
How does Qbrexza work?
Qbrexza works by blocking the action of acetylcholine, a neurotransmitter that stimulates sweat glands [1]. By inhibiting acetylcholine, Qbrexza reduces the production of sweat [1].
How is Qbrexza used?
Qbrexza is applied to the underarms once daily using a single cloth wipe [1]. The wipe should be used to dab the skin in the underarm area, and then discarded [1]. Patients should wash their hands with soap and water immediately after use [1]. It is important not to apply the wipe to broken or irritated skin [1].
What are the potential side effects of Qbrexza?
Common side effects of Qbrexza include dry mouth, dry eyes, blurred vision, and headache [1]. Less common side effects can include difficulty urinating, constipation, and dilation of the pupils [1]. Patients should consult their healthcare provider if they experience any side effects [1].

These include potential impacts on the eyes, mouth, urinary tract, and gastrointestinal system [1]. Patients with certain medical conditions, such as glaucoma or difficulty urinating, may be at higher risk [1].
